Hopping feeling

My 94 4.0 has a nasty shake at any speed over 45 mph? I've had the wheels rebalanced fixed a bad lower balljoint and it still does it.. Nothing else appears to be worn out.. Any suggestions

Out of round tires? swap front to back. Maybe lost weight/s on driveshaft or u-joint going.

Did you check axle pivot bushings, radius arm bushings, and sway bar bushings? My axle pivot bushings were toast.

All the bushing are good but I did just order the complete energy kit for it since the trucks 20 years old. How do you inspect the universals? I've never owned a 4x4 before so Im kinda lost.. Going from vw to ford is a big change lol

I think this may help you. In short universals can sieze up causing noise and vibration. They can also wear out causing loose fit and play. On your drive shaft, it could throw it off center.

Thanks.. it looks like I'm gonna be looking at them tonight when I change the rear gear oil

No problem. Look up the axle code in the door sticker. If you have limited slip, you need to add friction modifier to the gear lube. Just an FYI.
